Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to cultivate a field and to inject a chemical such as a soil disinfectant into the soil at the same time, and then cover the surface of the field with a film sheet having a predetermined width. Concerning the working machine configured to adhere the side edge of the already stretched sheet and the side edge of the unwound sheet in the adjacent stroke with adhesive tape to cover almost the entire field, A sheet that is equipped with a tilling device and a drug injecting device that injects a drug into the soil after tilling, and further forwards a film sheet of a predetermined width stretched to cover the surface of the soil on the rear side of the machine. A working machine provided with a feeding section, a lateral side edge of an already stretched film sheet, and a tape feeding section for feeding an adhesive tape for adhering the lateral side edge of a film sheet to be fed out. That.

[0002]

2. Description of the Related Art In the working machine having the above structure, conventionally,
For example, as shown in FIG. 7, a sheet roll 22 in which a thin resin film sheet S is laminated and wound in a roll shape.
From the above, the film sheet S is sequentially fed out and stretched in the field scene by the compression roller 26.
When unrolled from the sheet roll 22, the side edge of the sheet is sequentially wound from a state of being rolled and laminated,
Adhesive tape T fed from the tape feeding portion 35
There is a structure in which the adhesive tape T is also fed out together with the sheet being fed out and is attached to the existing sheet while being pressed by the spreading wheel 50.

[0003]

However, in the above conventional structure, the side edges of the sheet roll in which the film sheets are laminated and wound in a roll shape are such that the edges of the laminated state are always flush with each other. In some cases, the sheet rolls may not be aligned, or due to vibrations and the like associated with the above-described work, the stacked state of the sheet roll may be disturbed and each edge may be laterally displaced. In such a state, if the adhesive tape is directly attached at the sheet feeding part, the adhesive tape will stick to the sheet located inside the winding, and the sheet may be damaged or fed in a bent posture. However, there is a risk that the medicine may evaporate from such a place, and the sterilizing effect of the disinfectant may be reduced. The present invention aims to eliminate the above-mentioned inconveniences.

[0004]

According to a characteristic configuration of the present invention, in the working machine described at the beginning, a guide member for slidingly guiding a film sheet after being fed from the sheet feeding portion is provided, and the tape feeding portion is provided. The adhesive tape fed out of the guide member is sequentially adhered to the side edge of the film sheet which is slidably guided by the guide member with a part of the adhesive tape protruding outward from the side edge. There is a point.

[0005]

Operation: After the film sheet is unwound from a state of being laminated and wound in a roll shape at the sheet unwinding part in a single-layer sheet state, the adhesive unwound from the tape unwinding part is slidably guided by the guide member. Since the tapes are configured to be adhered one after another, when the adhesive tape is attached, the film sheet is always in a single-layered form, so that the film sheet is bent or double-adhered. It is possible to bond them smoothly without causing.

[0006]

Therefore, with the rational feeding structure, the adhesive tape can be smoothly attached to the film sheets, and the adverse effects such as the evaporation of the medicine from the gaps between the film sheets can be reliably prevented. , The bactericidal effect of the drug can be enhanced.

Embodiments will be described below with reference to the drawings. Figure 1
The walking type work machine is shown in. In this working machine, a rotary tilling device 2 is attached to the rear part of a walk-behind traveling machine body 1, and a film sheet S of a predetermined width stretched in a state of covering the surface of soil after tilling is sequentially fed out to the rear side thereof. The sheet feeding section 3 is provided, and the chemical injection device 4 for injecting and supplying the disinfectant into the tilling work field is configured. The traveling vehicle body 1 mounts the engine 7 on a front frame 6 that is cantilevered to the front of the mission case 5, and mounts the rotary tiller 2 through a rear hitch 8 provided on the rear side of the mission case 5. The transmission handle 9 is detachably connected, and a steering handle 9 is extended above the mission case 5 toward the front side of the body [the lower side in the traveling direction of the body].

A tool bar 19 is arranged along the lateral width direction in a state of being connected and fixed to a rotary frame 18 which is detachably connected to the rear hitch 8 and is fixedly attached to the tool bar 19. A support arm 21 extending from the vertical frame 20 constructs a sheet feeding portion 3 by erected and supporting a sheet roll 22 around which a thin resin film sheet S having a predetermined width is wound in a roll shape. , Sheet S to be fed out
A guide member 23 for slidingly guiding the middle portion of the above is erected and supported. Further, a pressure suppressing roller 26 that presses the sheet S in a grounded state by a support rod 24 and a vertical rod 25 extending from the vertical frame 20 in a front-back direction is arranged below the sheet feeding position.

The medicine injection device 4 includes the vertical frame 2
A medicine tank 28 for storing a disinfectant is placed and supported by a support tool 27 continuously provided on the upper part of 0, and a supply pipe 30 and four injectors are provided from the medicine tank 28 by a pumping action of a pump unit 29 described later. The medicine is injected into the field cultivated by the rotary tiller 2 through 31. Therefore, the medicine tank 28 is located on the center side in the width direction of the machine body so that the left-right weight balance is not lost. The pump unit 29 for pumping the medicine is configured to be rotationally driven by an electric motor 32, and as shown in FIG.
The electric motor 32 and the electric motor 32 are arranged in parallel with the power supply battery 33 along the lateral direction of the machine body so as to be detachably connected and supported to the front hitch 34 formed at the front end of the machine body to improve the front-rear weight balance of the machine body. I am doing it.

This working machine performs a so-called multi-work in which the surface of the field is covered with the film sheet S while the machine body is run toward the handle extension direction to perform the tilling work and the chemical injection work. At this time, in order to prevent the injected medicine from evaporating, the gap between the sheets in each work process is eliminated so that the entire surface is covered. That is, as shown in FIG. 2, an adhesive tape T for adhering the lateral one side edge of the film sheet S that has already been stretched and the lateral one side edge of the film sheet S to be fed out.
A tape feeding portion 35 for feeding the sheet, and after adhering to the side edge of the film sheet S that is slidably guided after being fed from the sheet feeding portion 3 in a state where tension is given by the guide member 23, the side edge is bonded. With a part of the tape T protruding outward, the adhesive tape T which is rotatably supported by the tape feeding portion 35 and wound in a roll is sequentially fed out and bonded.
Further, as shown in FIG. 3, the guide member 23 is provided with unevenness 36 on the outer peripheral surface at the guide portion of the adhesive tape T so that the adhesive tape T can be easily peeled off without being attached.

At the rear end position of the machine body, a sponge-like pressing wheel 37 is provided for adhering the adhesive tape T protruding outward from the side edge of the film sheet S fed out to the already stretched sheet S. It is rotatably supported and is provided with a rolling wheel 38 for embedding the side edge on the opposite side of the film sheet S in the soil and a soil gathering plate 39 in close proximity to each other. The inwardly embedded compaction wheel 38 is supported so as to be alternately switchable between an operating position and a non-operating position retracted to the upper side. That is, the arms 41, 42 supporting the respective wheels 37, 38 are integrally rotated around the horizontal axis X on the support arm 40 extending from the left and right sides of the toolbar 19 to the rear side of the machine body. It is configured so that it can be switched to each state. That is, the tape-tightening press wheel 37 is set to the operating state on the existing sheet side to perform the sheet S-sticking operation, and the soil embedding compaction wheel 38 is set to the operating state on the other side. The edges are buried in the soil. Since such a work is reversed right and left for each work stroke, the tape sticking pressure wheel 37 and the soil embedding compaction wheel 38 as described above are respectively arranged on the left and right sides, and it is necessary to switch them for each stroke. Becomes Then, as shown in FIG. 5 and FIG. 6, all the fields are sequentially covered with the film sheet S as the working process progresses, and the chemicals injected into the soil. Can be effectively prevented from evaporating from the gap between the sheets.

It should be noted that although reference numerals are given in the claims for facilitating the comparison with the drawings, the present invention is not limited to the configurations of the accompanying drawings by the entry.
